CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims benefit of priority to Korean Patent Application No. 10-2015-0167721 filed on Nov. 27, 2015 and Korean Patent Application No. 10-2015-0174924 filed on Dec. 9, 2015 in the Korean Intellectual Property Office, the disclosures of which are incorporated herein by reference in their entireties.

BACKGROUND

1. Field

The present invention relates to an outlet pump vessel of a liquid content which is able to intercept air, and more particularly, to an outlet pump vessel of a liquid content which is able to intercept air, which opens an inlet of a sealing nozzle through a liquid content is discharged during operation of a push button and closes the inlet of the sealing nozzle during non-operation of the push button to prevent the liquid content from being dried and solidified.

2. Description of Related Art

As disclosed in Korean Utility Model Registration No. 0408011, a discharge pump is generally mounted on a vessel and used as a means for discharging a small amount of gel-like contents contained in the vessel.

The discharge pump in the related art mounted on the vessel and discharging a small amount of gel-like contents is used for discharging the liquid contents in the vessel through a discharge nozzle by upward and downward movement of a piston and has an advantage in that the discharge pump can discharge and use an appropriate amount of liquid contents, but has a problem in that a nozzle inlet is continuously opened and air or various foreign substances flow through the discharge nozzle inlet, and as a result, the liquid contents which remain in the discharge nozzle are oxidized and deteriorated or the liquid content at the inlet is hardened.

Therefore, when the liquid contents are discharged and used through the discharge nozzle, the liquid contents that are initially discharged can not be used, and when the deteriorated liquid contents on the discharge nozzle are used without consideration, skin troubles are caused and reliability of a product is lowered.

In order to solve the above problems, a discharge pump that is designed to be able to close the discharge nozzle is contrived.

The discharge pump configured to close the discharge nozzle is disclosed in Korean Utility Model Nos. 233932, 241998, and 282740.

The pre-registered discharge pump has an opening/closing rod that can close the inlet of the discharge nozzle after discharging the liquid contents through the discharge nozzle.

In the pre-registered design in which the opening and closing is selectively performed by the opening/closing rod, the discharge nozzle is constituted by a nozzle and an opening/closing rod (insertion rod).

There are two types of discharge nozzles, for example, a discharge nozzle in which the inlet of the nozzle is closed by actuating the nozzle and a discharge nozzle in which the opening/closing rod that closes the inlet of the nozzle is actuated.

As described above, the discharge nozzle configured in such a manner that the inlet of the nozzle is closed while the nozzle or the opening/closing rod is actuated solves the above-mentioned problem. However, since a structure of the discharge nozzle is complicated, it takes a long time for assembling and production, and as a result, it is difficult to enhance productivity and production cost of the product increases due to diversification of peripheral parts for actuating the discharge nozzle.

Moreover, in describing the present invention, a detailed description of related known configurations or functions may be omitted to avoid obscuring the subject matter of the present invention.

Exemplary Embodiments

As illustrated in FIGS. 1 to 3B, an outlet pump vessel of a liquid content which is able to intercept the air according to a first exemplary embodiment of the present invention includes an outer vessel 2 containing an inner vessel 1 therein, a pump body 10 as a member of which an upper part screw-coupled to an upper opening of the outer vessel 2 having multiple steps formed on an outer circumferential surface, a cylinder 20 positioned inside the pump body 10 and in which an outer flange 21 is supported on an upper inlet 1a of the inner vessel 1, and an elevating device 30 which ascends and descends from the inner circumferential surface of the cylinder 20 by a pushing operation of a push button 40.

As illustrated in FIGS. 5 and 6, the third exemplary embodiment is the same as the first and second exemplary embodiments and is different from the first and second exemplary embodiments only in an internal structure. That is, in the push button 40 as a cylindrical member whose upper part is closed, an inner hole 41 which is in communication with the elevating rod 33 with the upper and lower parts opened, a side hole 42 which is in communication with one side of the upper part of the inner hole 42, the sealed nozzle 43 is inserted into the side hole 42, a “”-shaped push member 44 is installed, which is inserted through an upper hole 43a of the sealed nozzle 43 to push the lower part of the sealed nozzle 43 by the pushing operation and open a slit 43b formed at the front, and a horizontal rib 45 is formed so that the lower surface of the sealing nozzle 43 is inserted into the lower surface of the side hole 42.

Next, an action and an effect of the outlet pump vessel of the liquid content which is able to intercept the air configured as above will be described.

In order to use the outlet pump vessel of the liquid content, first, when a vessel lid 3 is removed, the push button 40 is pushed, and pushed together with the “”-shaped push member 44 which protrudes on the upper surface of the push button 40, the push button 40 descends and an actuating cylinder rod 32 descends in the cylinder 20 and while a space in the cylinder 20 is compressed, that is, reduced, the liquid content in the vessel introduced into the cylinder 20 through the check valve 50 and the introduced liquid content is sucked through the center of the actuating cylinder rod 32 and the “”-shaped push member 44 is pushed, and as a result, the lower end in the sealing nozzle 43 is pushed and the slit 43b is thus opened to discharge the liquid content to the slit 43b (see FIG. 3B).

In addition, when pushing of the push button 40 and the “”-shaped push member 44 is released, a cylindrical spring 34 is expanded and the push button 40 ascends and simultaneously, the vertical tip 44a of the “”-shaped push member 44 ascends and the slit 43b is closed, that is, upper and lower sides are in contact with each other to be sealed. The upper and lower sides are sealed to prevent the liquid contents of the cosmetics which remain on the transfer passage from being oxidized and deteriorated due to contact with the air or the liquid content at the discharge port from being solidified and hardened.

As described above, detailed exemplary embodiments have been described in the detailed description of the present invention, but a possibility that the technology of the present invention will be easily modified and executed by those skilled in the art is apparent and the modified exemplary embodiments will be included in the technical spirit disclosed in the appended claims of the present invention.
